You are now going to fit the top bar between the legs. Take a long bolt,
place a washer over the end of it and insert the bolt into the top right hand
hole and feed it through both frames, you will see it come out the other side.
Feed it into the hole in the end of the pole. Use the Allen key and turn the bolt
in a clockwise direction to secure the bolt. You will see the end of the pole
disappear into the hole in the frame. Do not over tighten the bolt at this point.
Repeat on the left side.
